I am a member of the Sports Car Club of America. I race a Showroom Stock B, Mazda Miata. I have been racing SCCA since 1980 and have many regional and national championships. I’ve won the SCCA Northern Pacific Championship in SSB for 2003 and 2004. I am leading the Southern Pacific Division for 2005. We run 8 to 10 National races a year and we always do the SCCA National Runoffs in Lexington Ohio. Starting in 2006 it will be held in Topeka, Kansas.

I have been using AMSOIL in my racecar for about 2 years and found 2 advantages over the oil I had been using for years previously. I noticed lower oil temperature and an increase in horsepower. I also changed my tow vehicle over to AMSOIL. I use AMSOIL engine oil, transmission fluid, differential lubricant, and diesel
fuel treatment.

My tow vehicle is a 2001 Holiday Rambler, 36 ft. diesel pusher. I immediately saw a 30° temperature drop in the engine oil and a 40° temperature drop in the transmission. That is very impressive!

To top it off, we saw an increase in fuel mileage. On a 5,000-mile trip, last year, we averaged 7.8 miles per gallon. The year before we averaged 6.3 miles per gallon. That is a very impressive improvement in mpg for a 30,000-pound motor home pulling a 24-foot trailer that weighs 6,500 lbs when fully loaded.

Another plus is the water temperature never went over 180° after I switched to AMSOIL. Before AMSOIL, the water temperature would go over 200° on small hills and I would have to turn off the A.C. to go up steep hills and I had to turn on the heater to cool down the water temperature.

(SVG) SEVERE GEAR™ Synthetic Extreme Pressure (EP) 75W-90 Lubricant
(GLC) Synthetic GL Series Multi-Purpose EP Greases
(AME) SAE 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil
